I wish I had an answer for you! Unfortunately, this one has stumped even professional mathematicians for over a century. It was first presented by mathematician Edmund Landau in 1912, and it’s gone unproven ever since. I can’t give you a solution, but I can definitely say you should submit your findings to a mathematical journal if you ever find one!
Answer:
First option: 
Step-by-step explanation:
The missing options are:

We know that "x" represents the number of weeks Bess worked and "y" the number of weeks Gina worked.
According to the data given in the exercise, Gina and Bess earn $45 per week for delivering flowers, this is:

Since earned an additional total bonus of $20, then the total money in in dollars that Bess and Gina earned for delivering flowers can be shown with the following expression:

Notice that this expression matches with the one shown in the first option.
Hi, you've asked an unclear question. However, I inferred you may want to know the actual number of students represented by the percentages of 27%, and 61%.
<u>Explanation:</u>
Finding percentage usually involves performing two operations; multiplication and division.
First, all (100%) of respondents said they watched TV at least at some point during the day.
Next, 27% of respondents stated that they only watched television during prime time hours, in which the actual number of students represented by the percentage is calculated by dividing 27 by 100 and multiplying by 1000 =
.
Finally, we are told 61% of respondents stated that they spend prime time hours in their dorm rooms. The actual number of students represented by the percentage is calculated by dividing 61 by 100 and multiplying by 1000 =

Answer:
the answer is 10 you round up a nine it keeps going to the end
